Prospects for Resolving the Puzzle of the Missing Antimatter

A cosmic excess of baryons (over antibaryons) is well-established, but the mechanism by which it is generated is not. It has long been thought that an explanation for this missing antimatter can be found within particle physics, though the Higgs discovery establishes once and for all that physics beyond the Standard Model is necessary to explain it. I will review the broad scope of the discussed resolutions and show how various, low-energy, precision measurements which search for the violation of discrete symmetries, most notably matter-antimatter symmetry CP and baryon number B, can help resolve Nature's favored pathway.
